Change IE Mode Engine in Edge Chromium

shockoMS 211 Reputation points

I'm running Edge Chromium v94. I'm testing out IE Mode but I don't see any way to on the fly change the IE emulation mode of a given site. In IE11 you could do this in developer tools. I need to test various sites in Ie11 Mode and IE5 mode. Is this possible or do I need to use an Enterprise Mode Site List?

    Hi @shockoMS

    You can't use F12 developer tools when you use Edge IE mode, so you can't change the IE emulation mode in F12 developer tools.

    If you want to debug in IE mode with different document modes on the fly, you can use IEChooser. You can open IEChooser according to the doc and in IEChooser you can choose different IE emulation modes like what you do in F12 developer tools.

    It's convoluted so personally I'd just switch to the actual IE to do the non-IE 11 testing. But if you want to do it in Edge you can do the following.

    Note 1: I assume you have already enabled IE Mode in Edge by going to the Settings options.
    Note 2: You'll need to install IE Tab extension.

    1. Load the page you care about.
    2. On the right of the address bar you should have a button that says "Reload tab in IE mode", click it
    3. By default it should load the site in the version of IE the says it supports.
    4. If that doesn't work for your case then you'll need to use an extension like IE Tab. That extension puts an E icon to the right of the address bar. Clicking it opens the site in an IE view.
    5. From there the "new address bar" has a settings icon to its right, click it.
    6. Under the options, at the bottom, is the list of IE compatibility modes that should match the settings from the old IE browser.

    IEChooser looks like the way to go. Thanks for the info.
